Question

Susie wants to write equations in the form ð‘¦=mð‘¥ b for the lines passing through point ð‘… that are parallel and perpendicular to line ð‘ . First she finds the slope of line ð‘ and line ð‘£ to be -23 and the slope of line ð‘¡ to be 32 . Point ð‘… is located at (2,2) . Which step could be used to find the 𑦠-intercepts?

1) Substitute the slope and the coordinates of point R into the equation ð‘¦=ð‘šð‘¥+b and solve for b
2) Substitute the slope and the coordinates of point R into the equation ð‘¦=ð‘šð‘¥+b and solve for ð‘¦
3) Substitute the slope and the coordinates of point R into the equation ð‘¦=ð‘šð‘¥+b and solve for ð‘¥
4) Substitute the slope and the coordinates of point R into the equation ð‘¦=ð‘šð‘¥+b and solve for m

Answer 1

To find the ð‘¦-intercepts, substitute the slope and the coordinates of the given point into the equation ð‘¦=ð‘šð‘¥+b and solve for ð‘¦.

Step-by-step explanation:

To find the ð‘¦-intercepts of a line passing through a given point and parallel or perpendicular to another line, you would substitute the slope and the coordinates of the given point into the equation ð‘¦=ð‘šð‘¥+b and solve for ð‘¦. So the correct option is: 3) Substitute the slope and the coordinates of point R into the equation ð‘¦=ð‘šð‘¥+b and solve for ð‘¦.
